Scientific context

The Internet of Things (IoT) as it is defined today aims at interconnecting physical objects using Internet technologies. This brings two complementary scenarios in the picture: Machine to Machine interaction, where connected smart objects can interact autonomously with each other, and physical world interaction, where sensors quantify their surroundings and actuators may act upon their immediate environment. These networks are envisioned as a major source of data, stored remotely in the cloud for later analysis, hence contributing to the rise of Big Data.

Project summary

Our main objective is to provide the means to operate a WSN with TSCH in a fully distributed manner, namely without using any centralized entities.
To reach this goal, our work needs to focus on MAC and routing. It will address three distinct but combined objectives:

compute and allocate, in a distributed way, global schedules of cells that will guarantee required properties — e.g. short delay;

compute suitable paths with a distributed routing algorithm on which to build the aforementioned schedules;

perform neighbor maintenance to discover new nodes and maintain connectivity with nodes of interest, on which we can rely to provide efficient routing.
